LUBRICANT- CONTAINER.

Specification of Letters Patent. Patented Jan. 24, 1911.- Applicationfiled April 29,

1910. Serial No. 558,504.

To all whom it may concern:

Be it known that I, HENRY I. CAmuMr 'roN, a citizen of the UnitedStates, residing at New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements inLubricant-Containers, of which the following is a full, clear, and exactspecification.

This invention relates to libricant containers, and has for its objectto provide a commercial package for containing lubricant or othercompressible materials which can be expelledlunder pressure.

The object of the invention is more particularly to provide a commercialpackage for greases or oils used in automobiles, which'can be put up inpackages, and can be supplied to the required parts when nec essary, thepackage when once emptied not ordinarily to be used again.

The use of compressible tubes for containing greases or lubricants isobjectionable because of the possibility of fracturing the, tubes beforethey are emptied, and this invention has especial reference to a tubularpackage which can be tilled with grease or oil and sealed until requiredfor use, the package or container preferably embodying a movable istonfor expelling all of the contents and at the same time sealing thecontents against damage by exposure. For operating the piston aseparable rod is provided, the forwardend of the package nor mally beingprovided with a closure cap which can be replaced by spouts of anydesired length and shape. In practice, a number of filled packages willordinarily be sold together, with common spout and operating means, sothat when one package is. emptied it can be thrown away and the spoutand operating rod used for the others. Thereby, a considerable, economy'in the use of greases is secured while the presence of foreign matteris avoided, and also parts of an automobile, for instance, which areordinarily difficult of access, .can be readily charged withoittinconvenience or waste.

'As herein specifically shown, the invention comprises a tubular bodyhaving at the forward end a nozzle provided with a removable cap whichcan be replaced by a spout, together with a stationary rear head and amovable/piston arranged to be operated by'a rod thrust through the. rearhead. In the "form shown, the rod has threaded engagement with the headin order to uniformly expel the lubricant material, and the piston isspecially constructed to receive the rod, and to expel practically allof the contents of the container.

The invention will be more full understood in connection with thedescription of the accompanying drawin s, in wh1ch Figure 1 shows anoutsi e view of the invention ready for use; Fig. 2 a sectional view,and Fig. 3 a sectional view of a filled package.

1 represents a casing having secured thereto a forward head 2 providedwith a nozzle 3, preferably screw-threaded to receive a cap 4. At therear end is a stationary head 5, which may be soldered to the bodyportion 1 and provided with a central perforation, which, as hereinshown is reinforced by a threaded nut 6.

7 is a detachable spout which can replace the cap 4 when it is desiredto fill a grease cup or other part of a machine. Various terms of spoutsmay be used, either straight or curved, depending upon the character ofthe machine.

Mounted to slide within the body 1 is a piston 9 consisting of agenerally cylindrical projection 10 adapted to loosely fit the nozzleportion 3 to expel substantially all of the,

which are mounted on pivots 12 short levers 13 normally pressed upwardby springs 14.

15 is a packing washer held by a ring. 16 and fastenin'gs 17. The rearside of the piston has a central hole beveled as at 18 to receive arod.19 which may be preferably threaded to engage the nut 6. The rod 19may be provided with a turning handle, as 20. The spring pressed levers13 tend to frictionally engage and center the lower end of the rod '19after ithasbeen guided through the beveled hole 18, so that turning ofthe rod does not turn the piston 19, while by turning the rod backwardit can withdraw from the piston 9.. It will thus be seen that the rod 19is simply efi'ective to operate the piston in one direction toward thenozzle 3 or spent 7, and when moved in the other direction disengagesfrom the piston S). It will be observed that the piston 9 is madesuflicielitly long to move evenly, withoutbeing upset as would be thecase with a narrow pistoni l ig. 3 shows my improved package in itscommercial form, from which it W11. be seen block, as shown in Fig. 1,having a forward 'grease or oil, and transverse slots 11 in grease orother material contained inthe tube protected from the air by thepiston.

When the grease is to be used, the cap may, be removed and a spoutsubstituted or not,

as maybe desired, while the rod 19 is inserted through the aperture inthe rear head. B turning the rod to advance it, the piston w ll beadvanced, and thereby the contents forced out from the forward end. Whensufficient has been used the cap can be replaced and thereby the wholeinterior kept free of dirt or deterioration by exposure to the air. Thespecific frictional,centering and holding means for the operating rodherein shown may be varied without departing from the scope of theinvention as may also I other details, it being seen that the piston isformed to center the rod and hold it during operation; \Vith some formsof more fluid lubricants it may not be necessary to thread the rod,though for handling heavy g reases for which this invention is moreespecially intended, a threaded rod is more advantageous. I-la'v1ng thusdescribed my invention, I

declare that what .I claim as new and desire 'to secure by LettersPatent, is'

A package for plastic material comprising a cylindrical body having aforward and a rear head composed of sheet metal, a nozzle 0n the forwardhead having means for locking a closure cap or an interchangeable spoutthereto, a closure cap, said rear head having a central aperture and athreaded reinforcing nut rigidly secured thereto, elongated in thedirection of the axis of the body and adapted to move in said body andcomprising a solid cylindrical block packed to engage saidbody, saidblock having a plug of smaller diameter adapted to move and' fit withinsaid nozzle when' in the extreme forward position and a central socketin its rear side, and a threaded "operating rod directly engaging thethreads of said nut and extending into and loosely e11- gagingsaid-socket in the piston, said rod being removable through the rearhead.

In testimony whereof I atlix my signature, in presence of two witnesses.
